SLE66C20S

SLE 66C20S is a member of the  Infineon Technologies high-end security controller family in 0.6 µm CMOS technology. The CPU provides the high efficiency of the SAB 8051 instruction set extended by additional powerful instructions together with enhanced performance, memory sizes and security features.

The controller IC SLE 66C20S offers 31.5 Kbytes of User-ROM, 256 bytes internal RAM, 1 Kbyte XRAM and 2 Kbytes EEPROM. It suits the requirements of the new generation of operating systems.

The random number generator (RNG) SLE 66C20S is able to supply the CPU with true random numbers on all conditions. The CRC module allows the easy generation of checksums according to ISO 3309 (16-Bit-CRC). The timer makes it easy to implement advanced communication protocols such as T=1 and all other time critical processes. An additional interrupt capability of the I/O module allows parallel operation of chip card and terminal. To
minimize the overall power consumption, the chip card controller IC offers a sleep mode. As an important measure, the chip provides a new and enhanced level of on-chip security features.

In conclusion, the SLE 66C20S  fulfills the requirements of all chip card applications, as especially Loyalty, Leisure Cards, Health Care, payment, Access Control and prepaid SIM Cards for GSM Phones. The SLE 66C20S is a powerful chip card controller IC integrating outstanding memory sizes, additional peripherals in combination with enhanced performance and optimized power consumption on a  minimized die size. Therefore, the
SLE 66C20S offers the basis for new chip card applications.
